Overmolding Services
When a metal, plastic or ceramic part needs to be embedded in plastic to improve product structure it is called

Insert Molding. It is a widely used process.

Plastic Overmolding Services

Overmolding process is a unique injection molding process. After injection molding the internal base material (usually metal and plastic materials with higher hardness), it is placed in overmolding molds for molding and cooling.

 

When the injection molding parts you need need to take into account the characteristics of sturdiness, practicality, beauty, etc., you must consider using injection overmolding. This is an efficient and cost-effective molding process, suitable for multifunctional injection molding solutions in all walks of life.

 

Generally, overmolding is an injection molding technology that effectively reduces costs and is widely used, and requires rich manufacturing experience and high mold manufacturing standards. It can quickly reduce the cost of secondary assembly of traditional plastic parts, as well as applications that do not require harmful glue, and can achieve stable quality, high efficiency, and reduce the risk of defective products during mass production.

Types Of Overmolding

According to the different application requirements of the product, we can take several different ways to carry out plastic overmolding, the main difference is the combination of different materials.

Rigid plastic overmolding process:

After the internal base material is made of rigid plastic injection molding, another type of steel plastic is wrapped around the base material through an overmolding mold. The color of the material can be customized, but the material compatibility limit should be consulted. Otherwise, cavities or cracks will occur.

Rubber overmolding plastic:

The internal base material is made of steel plastic. After molding, the rubber material or TPE material is wrapped on the surface of the base material. The product presents the softness of rubber and can play a role in wear resistance and non-slip, such as: toothbrush handles, electric tool handles, etc.

Plastic overmolding metal:

We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the plastic around the metal substrate at one time through overmolding, such as: pipe connectors , Electronic components, etc.

Rubber overmolding metal:

We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the rubber material on the surface of the metal substrate through overmolding to present a soft rubber layer. Such as fitness equipment, medical supplies, hammer handles, children's toys, etc.

Advantages Of Overmolding

We can come into contact with toothbrushes every day. Its base material is injection molding made of steel plastic, which is very hard and tough. The rubber handle on the handle can effectively help us to prevent slippage, and can improve the color matching and aesthetic appearance. The product is derived from the overmolding process and is suitable for mass production.

 

● Improve product surface friction

● Can achieve a more ergonomic design

● Improve product electrical insulation

● Create products with better sealing

● Effectively isolate vibration and sound transmission.

● Improve color matching options and improve aesthetics.

● Reduce the use of harmful adhesives and other consumables.

● Increase manufacturing efficiency, suitable for mass production.

● The product structure is not restricted, and the adaptability is high.

What Is Plastic Overmolding Services?

Overmolding a variety of different plastics is a powerful plastic injection molding process that is aesthetically pleasing and can effectively improve product functions and performance. It can present perfect seamless splicing through advanced manufacturing technology and is widely used. Similar to it is another type called Two-shot injection molding, or 2K injection molding also known as Double shot injection molding. But there are some key differences.

We will elaborate on the differences in another article.

The Difference Between Overmolding & Insert Molding?

Although the plastic molding process applied to different products is very similar, there are still very obvious differences. For professional manufacturers, it can be easily distinguished, but for some non-professional buyers, develop a Which process is more reasonable for the product is a topic worthy of attention.

Why Use Overmolding Services?

In many cases, overmolding is the most direct manufacturing process to change product performance.

To add soft touch, attractive appearance, increase friction and enhance sealing performance to the product, the overmolding process can solve all your needs with high efficiency and low cost.

The following is a comprehensive analysis of our manufacturing experience for you:

 

● Enhance Product Performance

The basis for the product to be well received in the market is that it has powerful functions when used. Non-slip, soft and beautiful are all conditions to attract customers.

For example: TPE overmolding parts can take advantage of the softness and non-slip characteristics of TPE, which is not only comfortable but also beautiful in use, and is widely used in medical surgical instruments and other fields. And the anti-vibration and cushioning properties of TPE are widely used in electronic chip components.

 

● Attractive Appearance

Monotonous metal texture and plastic texture products can no longer satisfy the current consumer aesthetics. More and more color splicing and matching can attract customers' attention in a short time.

Overmolding process can be very free to combine and match the color of the material, presenting a comfortable visual effect, and this custom color does not need to pay too much cost, and does not need to change the cost of mold investment.

 

● Reduce Costs

The reason why overmolding parts are widely used is that they can bring more added value to the product. This does not change any cost composition. While maintaining low costs, it replaces welding, gluing, threaded assembly and other methods, which not only reduces labor costs, but also It can improve production efficiency, maintain quality stability, product appearance consistency, and reduce quality risks caused by human error.

Is My Project Suitable For Overmolding Process?

Overmolding is a more complex plastic molding process. Compared with isert molding and injection molding, it weighs many factors. Please send your product design and requirements. We will provide you with all-round technical support as soon as possible.
